>> Global warming is on hold on the Antarctic peninsula, at least for a while. A team at the British Antarctic Survey say a 50-year trend has been reversed. This, in part of the world that's seen some of the fastest temperature rises recorded on Earth. Reuters environment correspondent, Alister Doyle says the hole in the ozone layer may be to blame, changing local wind patterns.
I think that this is due to just regional local changes in the climate. It could also be related to the ozone hole which has been gaping over Antarctica in recent decades. Because of a buildup of man-made chemicals in the atmosphere, mostly from refrigerants. The Cambridge-based team say it's a blip, and they're predicting more severe warming as the century progresses.
The buildup in greenhouse gases globally is causing the atmosphere globally to warm up. There are plenty of places in the earth where warming doesn't track the rates of global warming. Tracking antarctic temperatures matters. Scientists warning if the continent's ice shelves melt, glaciers could empty into the sea much faster.
Raising sea levels by as much as six meters, swamping coastlines from Florida to Bangladesh and threatening cities from Beijing to London.
